U.S. Provisional Patent Application No. 60/982,700 entitled “System and Method for a Light Weight Server Installer,” by Akbar Ali Ansari, filed Oct. 25, 2007, Attorney Docket No. ORACL-02291US0.

COPYRIGHT NOTICE

A portion of the disclosure of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.

FIELD OF THE INVENTION

The invention is generally related to Java-based application server environments and in particular to a system and method for a server installer.

SUMMARY

Disclosed herein is a system and method for a light weight server installer. Existing application server installers limit the user to selecting which software product to install. This provides an inadequate level of control to users who require only a subset of the functionalities available in a given software product. This leaves the user with functionality that he or she may not use, wasting disk space and install/startup time. This also increases the size of the installer and the size of the footprint of the installed application server. For example, in the case of Weblogic Server by Oracle Corporation of Redwood Shores, Calif., the installer requires about 700 MB of disk space and the minimum installation requires 525 MB. A light weight server installer with finer grained installation options can be useful. In one embodiment a light weight server installer is provided which can enable a user to install an application server, such as a Java Platform Enterprise Edition compatible application server with no additional functionality. The user can then select the functionality he or she requires and the light weight server installer can install only the components necessary to implement the selected functionality. In another embodiment the user can use a graphical user interface to make his or her selections. In another embodiment the light weight server installer is an internet installer, enabling the user to download over the internet only the components necessary to implement the selected functionality.

 DETAILED DESCRIPTION Light Weight Server Installer

A light weight server installer can provide finer grained installation options in order to provide a smaller download and installation footprint. The light weight server installer can include technologies essential for application server runtime and production execution as well as optional components.

The light weight server installer can support component installations and uninstallations that allow the user to install additional components, to add functionality, or uninstall currently installed components, to remove functionality. These finer grained installation options enable the user to select which components of the application server to install to limit the installation to the user's needs.

For example: Options A, B, and C are available for installation. The customer can install option A in the initial installation. Later, the customer can install options B and C in addition to option A which was already installed. Likewise, if options A, B, and C are installed, the user can uninstall option B at a later time, provided that the remaining options do not depend on option B.

One embodiment includes a light weight server installer. The light weight server installer can include a plurality of selectable options including a core application server and a plurality of optional components. The optional components can include an administration console, at least one library, and at least one driver. In one embodiment, the light weight server installer installs only the selectable options selected by a user.

FIG. 1 shows graphical user interface (GUI) 100 in accordance with an embodiment. Frame 102 lists the selectable options available. In Frame 102, the Core Application Server and Administration Console under WebLogic Server and Workshop under Workshop for WebLogic Platform are selected; Administration Console is highlighted. Frame 104 contains a description of the highlighted selectable option; here it shows a description for Administration Console. Frame 106 shows the disk space required to install the highlighted item and the disk space required to install all selected items.

Enhanced Package Installer

In one embodiment, the light weight server installer is an enhanced package installer which can provide more install options for an application server. A package installer can contain all of the software necessary to install an application server and all of its options. With a package installer, the user can download the entire installer before running the installation program. Package installers can also be placed on a DVD or other storage media for physical distribution. The enhanced package installer can also be used to install additional software components in an existing application server installation. Additionally, an enhanced package uninstaller can individually uninstall previously installed components. The enhanced package installer can show the disk space required to install a component.

FIG. 2 shows an enhanced package installer in accordance with an embodiment. The enhanced package installer 204 can be delivered to computer 200 via a DVD or other computer readable storage medium 212. The enhanced package installer can come with all of the software needed to install all selectable options in the form of binary install files 202. In this example, the user can select 210 from among the selectable options presented using GUI 206. The enhanced package installer using 208 the binary install files then installs only those selectable options selected by the user.

In one embodiment, a light weight server installer can receive a selection from a plurality of selectable options. The plurality of selectable options can include a core application server and a plurality of optional components. The plurality of optional components can include an administration console, at least one library and at least one driver. The light weight server installer can install the selection of selectable options.

In another embodiment, a light weight server installer can be stored on a computer readable medium. When executed on a computer, the light weight server installer can receive a selection from a plurality of selectable options. The plurality of selectable options can include a core application server and a plurality of optional components. The plurality of optional components can include an administration console, at least one library and at least one driver. The light weight server installer can install the selection of selectable options.

In an embodiment, the light weight server installer can have inter-dependencies on selectable components built into the User Interface layer. For example a user trying to install an administration console must have the core application server option chosen or downloaded previously. All of the options can independently depend on the core application server. The interdependencies between install components can be defined in a Global Product Registry (GPR) xml file. In one embodiment the light weight package installer can be used on a computer running any operating system that has previously installed a Java Development Kit.

In one embodiment, the light weight package installer can offer a selection of Java Development Kits (JDKs) to install. The light weight package installer can include appropriate JDKs for the operating system of the target computer.

At installation scripts can be generated which point to installed Java Virtual Machines (JVMs). Scripts can be generated as per following rules:

    • 1) If a user selects one of the JVMs, scripts will point to the selected JVM.
    • 2) If a user selects multiple JVMs, scripts will be generated based upon current heuristic algorithm.
    • 3) If a user tries to install one JVM after previously installing a different JVM, the generated scripts will not be modified. Instead a warning will be displayed indicating that the user needs to manually modify scripts in order to reflect the new JVM.

Internet Installer

In one embodiment the light weight server installer is an internet installer. The internet installer can contain functionality to expose a set of downloadable software components and download those software components selected by the user over a network from a remote server and install them locally in a user-defined location. The internet installer can delay the actual download until the user has exercised his choice. The internet installer serves the needs of the users who do not want to download monolithic install bits before actually installing the product.

The internet installer can enable a user to download a small installer that then enables the user to select other application server options to install. For users who already have a suitable Java Development Kit (JDK) installed, the small installer download is on the order of 10 MB.

FIG. 3 shows an internet installer in accordance with an embodiment. The internet installer 304 can be downloaded 310 to computer 300 from the internet 302. The user can select 308 from among the selectable options presented using GUI 306. The internet installer downloads 310 only the install files corresponding to the selectable options selected by the user from the internet. The internet installer then installs only those selectable options selected by the user.

In one embodiment, JDK download and installation options can be selectable from the internet installer. In one embodiment, the internet installer can support downloading an installation of a core application server only. In one embodiment, the internet installer can also support the installation of additional components without unnecessarily re-downloading a JDK or other previously installed options.

In one embodiment, the internet installer can be used on any computer regardless of the operating system of the computer. In this embodiment the target computer already has a Java Runtime Environment (JRE) installed.

In another embodiment the internet installer can be configured to run only on a specific operating system. In this embodiment the internet installer installs a JRE on the target computer where the JRE is operating system specific.
